商品描述

Introducing JCAT's newest flagship linear power supply, the ULTIMO. One transformer, one rail, one DC output voltage, one DC output. This is the best sounding way to make such a power supply. 

NO COMPROMISES – THE EPITOME OF POWER AND CLARITY. 

Inspired by the legacy of the OPTIMO 3 DUO, the ULTIMO is crafted for the most discerning audiophiles.

        • KEY FEATURES

              • Larger Bespoke Transformer: Custom-ordered based on our design with reduced inductance and minimal stray field. Magnetically and electrically shielded, it operates entirely in the linear section of its magnetic core’s characteristic.

              • Silicon Carbide Diodes: The semiconductor SiC technology, far superior to silicon diodes, features virtually zero turn-off time and negligible oscillations. This reduces noise levels significantly when compared to standard semiconductor rectifiers, a primary noise source in linear power supplies.
              • Three-stage Topology: ULTIMO boasts two regulation stages with a voltage buffer in between. Voltage post the initial stage is buffered at a very low impedance to enhance the power supply’s dynamic attributes, which then proceeds to the second stage. This configuration ensures optimal working conditions for the final output stage, minimizes its thermal load, and isolates it from low-frequency disturbances emerging from the AC voltage rectification process. The ultimate sound quality is guaranteed.

              • Minimal Noise Pathway: An innovative JCAT-designed PCB technique, optimizing component placement for noise filtration right at the source, ensuring the shortest return path.
              • Short & Symmetrical Current Pathway: Ensures consistent energy delivery.
              • High-Grade Non-Magnetic Chassis: Crafted from quality anodized aluminum, this mechanically optimized enclosure guarantees optimum sonic attributes.
                • Superior Build Quality: Only the finest components. 2oz copper-thickened, gold-plated PCBs. The ULTIMO and all its components are proudly made in Poland.
                  • ULTIMO DC Cable: As a companion to our flagship power supply, we’ve designed the best possible DC cable. Crafted from 14AWG OCC copper, it is shielded with minimized impedance and a unique structure that reduces mechanical vibrations. With a power supply as advanced as the ULTIMO, this top-tier DC cable is essential to unleash its full potential. The ULTIMO DC can be purchased separately as an upgrade for OPTIMO 3 DUO PSU.
